Scenario: ClearPass 6.7
Switches: Cisco 3650 (3.0.6.06E) and Brocade FCX648S (8.0.30n)
We have a implemented a mac-auth service policy for Shoretel phones. The enforcement profile on this service assigns a RADIUS IETF Session Timeout value of 28800 (8 hours). On a Brocade switch in our lab using the same CP servers, the phones re-auth every 8 hours, as expected. However on a production switch with identical configuration the phones re-auth randomly, e.g. 1 hour, 45 minutes, 20 minutes, etc. We've not experienced this issue on Cisco switches. We've opened a case with HPE support and they are pointing to the switch as the issue. However, we've yet to identify the problem. Just curious if anyone else has experienced similar issues and found a resolution?
